What Are Some Nanotechnological Approaches to Mitigation?
Nanocatalysts Nanocatalysts are materials that can enhance chemical reactions at the nanoscale. They can be used in catalytic converters to transform SO2 into less harmful substances like sulfuric acid or sulfur. Common nanocatalysts include titanium dioxide (TiO2) and zinc oxide (ZnO).
Nanoadsorbents Nanoadsorbents are materials that can adsorb gases or liquids onto their surface. Materials like carbon nanotubes and metal-organic frameworks (MOFs) are highly effective at capturing SO2 due to their large surface area and porosity.
Nano-Coatings Nano-coatings can be applied to surfaces to make them more efficient at reacting with or capturing sulfur dioxide. These coatings can be used in industrial chimneys, power plants, and even on vehicle exhaust systems to reduce SO2 emissions.
